Analysis of Scattering by Essentially Convex Bodies Using the Directive Source Integral Equation (1096)

A directive source integral equation (DSIE) approach is proposed for the analysis of scattering from essentially convex impenetrable objects. The DSIE augments the conventional equivalent sources located on the surface with fictitious electric and magnetic currents placed inside the volume originally occupied by the scatterer. These electric and magnetic currents are designed to absorb and suppress the radiation of the on-surface equivalent sources towards the interior of the scatterer.
